SPECIFICATION forming part of Letters Patent N 0. 256,612, dated April18, 1982.

Application filed September 9, 1881. (ModeL) To all whom a may concern:

Be it known that I, ROBERT H. AVERY, a citizen of the United States,residing at Galesburg, in the county of Knox and State of Illinois, haveinvented certain new and useful Improvements in Cultivators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit ap- Io pertains to make and use the same, reference being had to theaccompany ing drawings, and 'to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to cultivators of that class in which theplow-gangs are arranged to cultivate both sides of a row of plantssimultaneously, and are drawn by an axle or frame mounted onsupporting-wheels, to which axle or frame said wheels are hinged, sothat they zo-may be deflected or swung obliquely to the frame for thepurpose of changing the direction of the path of the cultivator when in'operation in the field.

The principal object of this invention is to 2 provide .novel meanswhereby the operator may deflect the wheels on the frame simultaneously,and thereby change the direction ofthe path of the frame and plow-gangsand to this end this invention consists in the use of arms 0 projectingfrom the wheel spindles or journals, which arms are connected in suchmanner that both wheels may be deflected in the same direction and atthe same time.

A further object in the invention is to provide novel means whereby theoperator, in swinging the rear end of one of the plow-gangs to eitherside, will thereby deflect both sup porting-wheels so as to move theaxle or frame, and thereby the forward ends of the plow 4o beams organgs, over toward that side of the path of the cultivator toward whichhe swung the rear end of the plow-beam; and to this end the inventionconsistsin combinations of parts and constructions hereinafter described5 and claimed.

In the accompanying drawings, which illustrate my invention, and inwhich the same reference-letter indicates the same part in the differentfigures, Figure l is a perspective;

0 Fig. 2, a top plan; Fig. 3, a side elevation;

Fig. 4, a perspective of one end of the axle, partly broken away to showthe hinge.

Referring to the drawings by letters, letter A represents an ordinarycultivator-axle, with an elevated central part, a, side parts, a, 5 5horizontal end parts, a, the outer ends, a, of which are hinged to theparts a, as hereinafter described. y

B is a tongue fixed to the elevated central part of the axle and bracedby rods 12. 4

00 are the supporting-wheels,journaled on the parts aof the axle. Theinner ends of the parts a are bent upward at right angles to the partsa, and are journaled at their upper and lower ends in brackets 11" onthe ends of the parts a, as shown at Fig. 4, whereby the wheels may bedeflected or swung, as indicated by dotted lines at Fig. 2. This axlemay be constructed in any desired manner, the tongue fixed upon it inany desired manner, and the wheels fixed thereon in any desired mannerwhich will permit of swinging them, as herein described and as wellunderstood at this time by those skilled in the art.

D D are plow-gangs of ordinary construc- 7 5 liOU, and may have ordinaryhandles when it is desired to use the implement as a walkingciltivator.Each plow-gang has a bracket, d, at its forward end, which embraces ablock,E, and is hinged thereto by a vertical bolt, 0, so that the gangsmayloeswung laterally thereon. The blocks E are slotted "critically, anda stirrup, F, which embraces the end a, of the axle, passes through saidslot, and has nutsfon its outer end. i 8 The blocks E may be adjusted inhigher and lower planes, and held after adjustment by the nuts f, forthe purpose of governing the depth of penetration of the soil by theplows.

The stirrup F may be adjusted at different 0 locations on the part a,and held also by the nutsf, for the purpose of adjusting the distancebetween the plow-gangs. A plate, G, is bent at its ends to encircle thepart a of the axle, and the edges 9 of its central portion pro- 5 jectrearward to form a rest for the block E. The stirrup F passes around theplate or sleeve G, and the plate G turns on the part a. of the axle topermit of swinging the plow-gangs in vertical planes. 10o

His a bar secured to the tongue B, and I is a bar pivoted thereto at itsmid-length portion at i. The outer ends of the bar I are connected bylinks t" with the upper ends of cranks or arms J, which project upwardlyand inwardly from the parts a, so that by oscillating the bar I, thehinged wheels 0 C may be swung simultaneously and in the same direction,as indicated by the dotted lines at Fig. L. An arm, I, extendsrearwardly from thebar I, by means of which the bar I may be oscillated.

K is abar which maybe reciproeated lengthwise of itself and transverselyof the cultivator in stirrups k on the rear end of the tongue. A pin, k,may be passed through a hole, la", in the bar K, and a hole, i, in thearm I, for securing them to each other.

L is an arm, hinged at its lower end to the side of one of theplow-beams or gangs I), and its upper portion passes through one of aseries of holes, 70 in the outer end of the slidebar K, to permitadjusting the bar L laterally in the bar K to correspond with thelateral adjustment 0! the plow-beams. The arm L is stayed by a slottedplate, M, secured to the plow-beam, as shown.

N is a'bar fixed to therear end of the tongue, and hasa hole,n.Bypassing thepin is through the hole in the arm I and the hole in thebar N the arm I will belocked and held from movementendwise, and willthereby hold the wheels from being deflected when desired. With the pinit removed from the arm I, so as to leave it tree to move, said arm maybe taken hold of by the operator and used in the evident mannertodeflect the supporting-wheels, and thereby control the path ol thecultivator, w hetber the arm L is t-onnected with the bar K or not. Thearm L passing through the holein the bar K will slide in said hole andnot interfere with raising and lowering the rear end of the plow gang orbeam; but when said gangor beam is swung laterally the arm L will slidethe bar K, and thereby dellect the wheels 0 O, or swing them in adirection to carry the front ends of the plow-gangs over toward the sameside toward which the rear ends of the gangs or beams were swung, andthus enable the operator to quickly and easily move the plows towardeither side to avoid plants out ot line, or for other purposes.

It will be readily seen that the crank-arms J may be differentlyconstructed from what I have shown, and that the device for connectingthem may be variously constructed and arranged, and may be connectedwith the plowgang differently from what I have shown; so 1 do not limitmy claims to the precise construction nor arrangement of these parts. doI limit my claims to cultivators having tongues or draft-poles, as itwill be seen that the main features in theinvention may be used in acultivator withouta tongue by supposing the tongue to be removed forwardof the axle and the remaining portion to be secured to the axle; but

What I claim, and desire to secure by Letters Patent, is-

1. In combination with the axle and wheels hinged thereto and armsprojecting Irom the wheel-spindles, the transverse pivoted bar I andlinks i, connecting the arms J, a bar, I, extending rearwardly from thebar I,by means of which the bar I may be oscillated and the wheelsdeflected, substantially as and for the purpose specified.

2. In combination with the axle or frame having swinging wheels witharms J, the bars I I, sliding bar K, and plow-beam D, the rods or armsL, adapted to move the wheels by the lateral movement of the plow-beam,substantially as and for the purpose specified.

3. In combination with the bars I I for operating the swingingcultivatorwheels, and with the sliding bar K, the rigid bar N, to whichthe bar I may be locked, substantially as and for the purpose specified.

4. In combination with the sliding bar K and plow beam or gang, the rodL, adapted to move freely in the bar K to permit the plowbeam to swingvertically without moving the bar K, and to move said bar-K whentheplowbeam is swung laterally, substantially as and for the purposespecified.

5. In combination with the axle or frame having swinging wheels witharms J, the links 2', bars I I, sliding bar K, having a series ofadjusting-holes, k anti plow-beam D,the rods or arms L, adapted to movethe wheels by the lateral movement of the plow-beam, substantially asand tor the purpose specified.

In testimony whereof I afiix my signature in presence of two witnesses.
